Using the Engine CLI
Use the engine CLI to change the engine IP address, Extreme Management
Center server IP address, and web service credentials. Use Extreme Management
Center to make these changes, if possible. You can also use the CLI to change
basic network settings such as engine hostname, SNMP configuration, and date
and time settings, if necessary (see
Using Extreme Management Center
).
Changing the Extreme Management Center Server IP Address
To change the IP address of the Extreme Management Center server, enter the
following command at the engine CLI:
/opt/nac/configMgmtIP <IP address>
Then, start using the new Extreme Management Center server by typing:
nacctl restart
Changing Web Service Credentials
The web service credentials provide access to the Access Control Engine
Administration web page and the web services interface between the Extreme
Management Center server and the Access Control engine. Engines ship with a
preconfigured default password.
If you change the web service credentials in Extreme Management Center (in the
Engine Settings), the new credentials automatically propagate to the new
engine when you enforce the engine.
In the event that you need to manually change the web service credentials on the
engine, enter the following command at the engine CLI:
/opt/nac/configWebCredentials <username> <password>
Then, restart the engine by entering:
service nacservices restart
Changing the Engine IP Address and Basic Network Settings
To change the engine IP address, as well as basic network settings such as
hostname and SNMP configuration (including system contact, system location,
trap server, SNMP trap community string, SNMP user, SNMP authentication, and
SNMP privacy credentials), enter the following command at the engine CLI:
